hi, is there any possibilities to connect 4 power supply unit together in one rig ?thank you

dude there are many rigs.

a few can use 3 psu's the s-9 can do that.

now gpu rigs with risers can use many psu's if wired correctly.

some gpu rigs have 19 gpus's in theory you could use more then 4 psu's if you wire it correctly

In all the cases above if you wire wrong pop you fry the gear
